Specification of Letters Patent No. 26,702, dated January3, f

To all whom it may concern; I

Be it known that I, M. OBERMILLER, of Tiffin, in the county of Seneca and State of Ohio, have invented a new and useful Improvement in Railroad-Car Brakes; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawing, forming part of this specification, in the several figures of which similar characters of reference denote the same part.

Figure 1 is a bottom view of railroad car with my brake attached. Fig. 2 is a vertical, longitudinal section of the same. Fig. 3 is a vertical transverse section showing back of truck. Fig. 4 is a sectional view showing the action of the spring detent. Fig. 5 is a sectional view of the lever caught by the spring detent in position for stopping the car. i l

The nature of my invention consists in a certain combination of devices,which upon the engine being reversed, act upon therubbers and stop the train, beingheld in their position by a spring detent, and are released simultaneously throughout the train by the conductor or engineer pulling a cord at the top of the car.

The devices consist of a combination of several levers with the drawbar aotingupon the rubbers, and forcing them against the Wheels, and a spring detent which holds said levers in position, until the drawing of the cord by the conductor or engineer forces away the detent, and by means of their several connections removes the pressure of the rubbers from the wheels, in the manner as will be hereafterdescribed.

In the drawing A is the bottom. of the car, B, B, the trucks, 6 the rubbers, c the springs, which act on the crosspieces connecting the rubbers, so as to keep them away from the wheels during the moving of the train.

a is a lever connected by rod 6 with the back crosspiece of the rubbers e.

D is the draw bar; havinga projection h I which acts on lever Efand forcesjit backi 5 until caught by spring detent f, andaslever E is connected with the crosspieces oft-he rubbers they are 1 this means pressed against the wheels; d. istheeord connected with lever H, by thepullinglofjwhich lever 3 H is drawn up, and presslngivagainstithe spring detent f, forces it back and allows the 155 lever E to resume its position, and by means removed from the wheels, i. The reversing of the,eng1ne causes-the} of the difierent connectionstherubbersare1 cars to be throwntogether and pushes backQGO 2 the draw bar D, the projection h of lwhich catching against the leverE pushes itbacklqf when it is caught and held by the springfdel tent f, and the lever E beingconnected withi lever 0!, draws lever a forward whichflby ce means of its connection 9131: and} rod buwith l the crosspieces connecting, the rubbers presses the rubbers against the wheels and effectually stops their motion. On starting, again the pulling of cord d draws up1-the 11 lever H, which pressing against; the spring detent f, also forces itup, andyallows the 1 levers E and a to returnto their-formerpo sitions, and removes the rubbers fromthe I wheels, the springs c acting against their con? f nectmg pleces, and keep ng; them away from V I the wheels.
